The overlay of animation on top of real footage is really cool to see. It helps give perspective of what parts are moving at what speed in real time. Great video!
The small puff of smoke after the round leaves the muzzle is from the air blast that is ported into the breach as the block is opened to avoid the mount housing and lower assembly from filling with propellant smoke.
While the ventilation is nice, it's actual primary use is to clear any un-burnt powder from the barrel, to prevent an unexpected flash.
I love using this video to show my civilian mates a bit of my job. As a 5 inch maintainer, this video is pretty spot on as a quick explanation, without going too much into detail. I love working on this gun and have been lucky enough to have the chance to fire it locally during a GFT.
Excellent animation, mixed in with an actually firing but being able to see what's going on inside. Love this
なるほどこうなっているのか。

You forgot to show the Gunners Mates taking turns sleeping in the Magazine.
it's a crappy video indeed
Best sleep I've ever had was atop a pallet of A576
Especially in Subic
That face when you're just a dirty GSM
You lads really do that?
then the whole boat smells like sulfur for hours. having the chance to shoot one of those guns was one of the best parts of my naval career.
What causes the sulfur smell?
@@hrgwea Sulfur, Cletus.
for hours........that’s nice of you.
i work at an Artillerie Ammunition Plant and i smells it all days .(also bad for health)
we made fuze, explosive filling, make increment charge and propellant bag for both mortar and artillery.
some day we burn expired explosive, fuze propellant charge, all my uniform smell of TNT for week, and air quality is just shit. we wear mask for week (before virus, after virus is mask all day)
but worsts of all is a guy at explosive smelting plants. those guys work with raw chemicals and explosives.
So did you guys discarde the empty brass? or did you collect it and return to the munitions maker? Also what targets are most likely for this gun? Can they take on other big warships (though I know that no one has battleships any more :( )

Back in the 1970's the MK45 I worked on was twice as fast as this. It had two loading drumbs in the Magazine, (two decks below the mount), and a double hoists taking the rounds to a twin carrier on the deck below the mount. The twin carrier would rotate the rounds to the guns orientation, where they were transfered up to the cradle in the mount which brought the rounds from vertical to horizontal. Once the rounds were horizontal the cradle would transfer it's round to the loading tray, to set any timed fuses, then to the ramming tray where it was rammed into the breach and fired. As the first round fired and recoiled, the breach would drop, the empty shell would be pulled from the breach into an ejector tray below the breach, where it was ejected under the barrell when the next round fired. We could fire 55 rounds per min, (and often did, as shore support in Viet Nam).
This configuration required a Gunner's Mate in the mount and another at a control panel in the carrier room. It also required at least 6-8 men in the magazine to keep drumbs full. The one shown in the representation here looks like it may require less manpower, but I would think double the firing speed is well worth the cost of a couple extra GM's.
Dang, now I want to see that visualized too

I’d love to see one of these animations on the Des Moines class 8”/55 caliber guns. If I’m not mistaken they’re still the largest self loading artillery pieces ever made.
ho ri cheese I forgot the Des Memes(Moines) got sum DPM/RoF
Same here
Possible but I believe the 8 inch cannon installed on the USS Hull DD 945 in the 70's where fully automated
Unless you mean autoloading, that's dead wrong. The largest self loading naval artillery would be the 18.1 inch gun of the Yamato, who did not require a single person for it's reload process.
3秒に1発の速度で30kmも飛ぶ弾撃ってくるんだから凄いよな
給弾システムも凄いけど、この給弾システムであれだけの速射能力を出せる事がもっと凄いと思う…第二次世界大戦頃の技術力だと多分同じシステムでも動力の差によってもっと時間がかかったと思う。

@@florinelenaradamilea what size were the old guns of the line?
@@CrackedCandy I don't quite get it, size or caliber but calibers went from 20mm all the way to 80mm. Of course there's the measurement Anglo in inches, from 5 to 15 & more, different ships sometime had a combo, pounders goes from 12 to 32. WW2 style went generally from 8 inch- 55. Some experimentation have been done with 18.1 inch. US settled for the 5/38 from ww2 & on.

Love the sound of the empty casings rolling on the deck.
I'm sure the boatswains mates don't 😂
@@jedisaki730 Lol.
They would sound much better if they were the old school brass versions!
It's even cooler watching the internal components work down below. The animation doesn't do it justice. One time we got a round stuck in the barrel (which is semi-common) and had to blast it out with a clearing charge. In local control, there's no automatic stabilization, so as the ship rolled, we fired into the water about a hundred yards off the port side. I was walking forward on the weather deck at the time. Scared the shit out of me lol
why the hell get rounds stuck in the barrel? corrosion? low temperature?
@@christofincognito4530 The projectiles have a soft copper ring around the outside called a bourrelet or rotating band. When the round is rammed into the gun, the lands of the rifling dig into the copper to form a tight seal. You can't get that round back out without firing it. Or at least not easily. So you use a smaller size powder can called a clearing charge to get it out.
@@billparker244 ok that explains how it is fixed, but what is the reason why it gets stuck? faulty round?
@@christofincognito4530 All ordnance has a failure rate, yes.
So what good is it to fire into the water? Couldn’t they have figured out how to compensate for that? Also, if a round got stuck wouldn’t that destroy the bore?
This is amazing! Do you think that you could do another video similar to this one about an older version of this gun, the 5”/38 caliber gun from WW2?
Excellent video, the combo of live action and animation makes it clear what an engineering marvel this gun mount is.
Was pretty cool to see the barrel track the target as the ship listed.

Take out the middle man. Pretty darn cool!
Eh, okay animations I guess. Would have been better if it included how the ammunition hoist worked and the rammer and the way the main magazine gets ammo to the hoist. But lots of boom boom so, it's pretty good.
the breech, hoist, rammer, the lift is kinda off as it is doesnt show how it move the projectile
You know,its still "classified"
It doesn't show the mechanism recoiling inside the turret either.
My guess would be compressed air acting as a rammer.
@@AbdurrahmanZedSaeed two parts of hoist: upper hoist, lower hoist, both powered by hydraulics. lower hoist is a chain system with two tubes like shown, one goes up on goes down. Upper hoist only goes up. when the drum rotates the a round will sit on the upper hoist, the shell goes up into the cradle and the cradle locks the shell and swing to gun elevation axis. A rammer powered by hydraulics which sits in the slide, ram the shell and the breechlock is dropped. after the cradle is lowered the round is fired and the slide recoils. Then a case tray lowers and the breech is opened, the extractor pulls back the shell and it sits on the case tray and it is ejected as shown above, meanwhile the cradle is lowered to receive another round.

The older Mk42 rate of fire was 40 RPM and had dual loading drums and dual sided loaders. The gun barrel was heavier. 3 of these guns with 1000-1200 magazines each like the old Forest Sherman I was on could put out 120 RPM. Of course you went into a hot gun situation pretty quick which was dangerous but you get the idea. Guns are no longer the Main Battery on a ship, hence the single and slower MK45
And they are mainly used for ground support and firing warning shots, so a reliable and light design is more important. The Mk42 where AFAIK downrated to 28 rounds per minute in the late 1960's and weighted about 60 tons per turret, while the Mk45/54 weights in around 25 tons with about 20 rounds per minute. The Bofors 120mm Model 1950 did 40-45 rounds per minute BTW, with destroyers having 4 or 6 guns each (in twin turrets), for a total of 160 to 270 rounds per minute. There was also later Bofors 120mm designs, designed to fire 75-80 rounds per minute per barrel, but they didn't see much use. In the US there was work on the 5"Mk Mark 65/66 as a alternative to the Mark 45, firing 48 rounds per minute per barrel with the Mark 65 having a single barrel and the Mark 66 two.
What happened when the ammunition inventory got low? I've seen footage taken from spotter planes in the Vietnam war showing multiple square miles of cratered land after being shelled by a battleship and it looks to me like an inconceivable amount of shells. Was it common to be resupplied with ammunition at sea or did the ships generally have to sail to a port for resupply? The scale of it all is very amazing to me: the guns, the boats, the logistics, and the engineering.
@@steventhehistorian Either by Underway replenishment or by heading to a port if it was close enough. Unrep in those days was mostly ship to ship. Vertical Replenishment is the prmary means at present.
Much improved over the Rube Goldberg mechanisms of the late 1940s.
How is that ?
It is definitely designed for people who are too lazy to load the guy.
The original system first used on the USS Salem's 3"/70 guns in the 1940s used a single rammer to do two functions. This system split the job between two rammers. Much simpler and more straightforward.
Also took the gunner out of the turret.
@@ghost307 or for people who realize it make more sense to have a robot which is faster, can't drop shit, takes up less space and can be ready to load the gun instantly without having to station someone in the gun makes more sense

@@concernedcivilianwilliam3396 Good to hear. Well if you have replicate your enemy's weapon system, but your enemy has a better weapon system than yours then start copying it to improve your current weapon system as well. Right?
@@jhonfloibelmiculob6581 yes, I guess you are right. But don’t worry about too much I reckon. As much as I like warship guns, they are not that useful in actual combat except bullying small ships and warning shots. This is my conception at least, somebody plz correct me if I’m wrong.
@@concernedcivilianwilliam3396 No need to correct you, I also got your point.
mechanical firing mechanisms are easy to replicate, the real secrets are the targeting computer/system, the propellant for the munition and the munition itself, really, modern ballistics theories have been around for over 100 years, this gun is mechanically simple to emulate

5-inch/54 is the correct nomenclature. The shell is 5 inches. The barrel length is 54 times the caliber (5 inches) which makes it 270 inches.
Great rendition!!!
去年からイベントがほとんど中止になり見に行けないのが残念。
What this video does not explain: how the casing and the shell are getting transported upwards. I mean: what drives them forward? And it is also unclear how the empty casings are getting out of the chamber?
Mere Freedom Magic
Magneto doing it
the empty casings are launched out by an extractor, basically a rod that catches the "lip" or rim of the propellant casing. not sure how similar it is to ground based artillery, but alot of extractors are cocked by the recoil of the gun to give it the necessary force to unstick the casings from the chamber.
@@MUJUNKY thank you. That is the same principle as for semiautomatic guns. But it was not shown here in this animation. And it is still unclear how the casings are ejected from the turret and before that how the ammunition gets elevated to the chamber.
@@ralfhtg1056 the ammo elevator is essentially a chain driven platform, it has a small floor or step attached, loads the new projectile and propellant into the drum, then the little platform folds over and goes back down. Not the best explanation, just drawing from memory of a video I saw. As for the mechanism that throws the casing out of the turret, I have no idea. You may try to find a video like "inside the turret Arleigh Burke" the TV show The Last Ship had some pretty cool inside the turret clips of the gun system working that may be what you're looking for.
Amazing system
Excellent video. Thank you.
To me, the interesting part is how the hoists and rammers work, but that wasn't included in the animation.

ローダーへの装填方法と排莢で薬莢が吸って吐かれる仕組みがよくわからないけど
P90みたいなアイデアでおもしろい。
これを見て模倣してKが付くとダメになるパターン。
装填は人力、薬莢は爪で蹴りだされます。
装填はチェーンラマー 排莢は銃と同じでエキストラクターを薬莢のリムに引っかけて排莢してる。
オートローダーの即応弾は20発 それ以外は人力装填
なるほどなるほど。
装填手は毎日50発とか100発の装填練習してるのかな？( ´ω`)
I wondered how they worked, now I know. Thank you 😊
Thanks!
1番好きな主砲の構造だ、、やったぜ
1967年ごろの自動装填薬莢排出システムが改良固定化されて、砲塔もアルミ合金化されて24tonに1/3軽量化が図られたとは、知りえなかった。1980年代以降の外形デザイン？のような感じがしながら、内部のメカニズムの少し古い感じのアンマッチ感が奇妙だと思ったが10~１５年前の設計確立凍結なら時代感覚にマッチする。大変良い3Dmotion.picturesでした。
砲の仰角を維持したまま給弾できるシステムになってるんですね。
なぜ薬莢を放り出すのか常々疑問だったんですけど、確かにこれだと
放り出す方が色々と安全かもしれないですね。
連射サイクルをあげるため、放り出さないとダメなんです。装填と排莢は連動してるので。
